I put in orders something like that when I buy stocks so that I can see how it gets posted. It's most likely someone doing the same thing.
"Sort of" is such a harmless thing to say. "Sort of". It's just a filler. "Sort of" - It doesn't really mean anything. But after certain things, "sort of" means everything. Like after "I love you" or "You're going to live" or "It's a boy".
